The Airsoft Predator shows how to make a Wolverine TTI “Dracarys” Gen-12 Extended Mag in this tutorial video... "Wanted to keep this short and sweet. Before you do this make sure it’s worth it here’s what I mean by that.

The main reason why I did this is because I had a bunch of 110 round SR25 mags laying around that I did not use & a lot of EPM1 Mags that I was willing to do this with.

Things that you should know before you do this:

If you don’t feel like converting and re converting back and forth between M4 & 308 Mags don’t do this.

They make 210rds mid cap magazines so if you would sacrifice those extra 40rds then just buy those ones.

If you don’t already have EPM1 mags laying around they are $32 a piece so keep that in mind.

If you already have EPM1 mags laying around you could purchase the 3D print files of 308 magazine shells."
